| 摘 要： | 针入度指数是评价沥青感温性能的指标,SBS改性沥青的生产原料、加工工艺条件对针入度指数的影响有较大差别,其中改性剂、基质沥青和增容剂对针入度指数的影响较大,因此研究不同因素对SBS改性沥青针入度指数的影响,可为SBS改性沥青感温性能的改善提供一定的参考。

| Abstract: | Penetration Index(PI) is used to evaluate the temperature susceptibility of asphalt.Some specifications such as the sources of SBS modified asphalt,processing condition have different effects on PI,among which modifier,matrix asphalt and compatibilizer have great effect.Thus,a study on the effect of different factors has been conducted so that theoretical basis will be provided to improve the PI of SBS modified asphalt. |
